Title: Road sweeping machine with entrainment system - has compressed air nozzles at the inlet directed to entrain debris
IPC: E01H1/08
Filed: 1973-11-28
Abstract: The road sweeping machine picks up debris and collects it into a storage tank. The suction effect for picking up is generated by blowing compressed air through nozzles, held in the picking up hose nose unit, inwards towards the hose. The debris loosened by rotating brushes in the vicinity of the picking up hose is entrained by air streams and debris is loosened by an impinging jet. The air stream passes through the convergent-divergent nozzle in the nose unit. Compressed air is provided by the compressor fitted on the vehicle. It is also possible to use vehicle engine exhaust gases. The air stream entrainment method is simpler than the alternative in which the collecting tank is held under vacuum.

Title: Monoflop assembled of digital components - has timing element determining the duration of the unstable state started by triggering pulse
Inventor: STRECKENBACH WULF-CHRISTIAN DI
IPC: H03K3/033
Filed: 1974-02-14
Abstract: The timing element is an electronic counter. The triggering pulse is applied to its one resetting input, and clock pulses are applied to its counting input through a controllable component. One of its outputs with different logic states is selected, which corresponds to the required duration. It operates the controllable component. When the triggering pulse is applied, the selected output terminal carries the logic state 'O', and is connected through an invertor to a first input of an AND gate. Clock pulses are applied to its other input, and its output is connected to the counting input, so that the clock pulses reach it only when the selected output carries the state 'O'. If the triggering pulse is applied to a NAND gate, one input through an odd number of invertors, and directly to its second input, then its output is connected through an invertor to the counter resetting input.

Title: Blasting rock by expansion of ice - uses object cooled in liquid air placed in water filled bore to cause sudden expansion
Inventor: LAMMERS ALBERT
IPC: E21C37/16
Filed: 1975-03-01
Abstract: The procedure for blasting rock or stone involves sudden and a strong expansion of the ice, achieved by immersing in water an object which was previously cooled in liquid air to a very low temperature. The ice formation takes place in an explosive manner with strong shock-type expansion of the ice. A small metal rod, or pebble, or other object, cooled in liquid air, is inserted in a hole drilled previously in the rock. The expenditure on liquefying a small amount of air is negligible compared to the cost of transporting and stoning in warehouses, broken rock, used for road building.

Patent DE-2518471-A1 (DE)
Title: Thermoplastic coverings for road-surfaces etc. - using an adhesive-covering material laminate
Inventor: LANGFORD WILLIAM JAMES
IPC: E01F9/04
Filed: 1975-04-25
Abstract: A material is bonded to a substrate by applying a heat-softening adhesive, to which the material is already bonded, to the heated substrate, or by using a material which is itself an adhesive, or by applying the material to the heated substrate and adhesive. The system may be used for, e.g., the application of road-markings, anti-skid surfaces, interior and exterior passageways, bridges, runways, parquet-flooring and building water-proofing. It shows advantages over other systems in that, in the case of painted road-markings, it is necessary to hold up traffic until the organic solvent content has flashed-off sufficiently. The system will give a more durable surface finish than will a paint system, the properties of the adhesive/coating system being adjustable to meet operational requirements, e.g. the effect of heavy traffic on road-markings. The adhesive will bond to bituminous and concrete surfaces, after correct surface pre-treatment, because it is bitumen-based. To the bitumen is added EVA copolymer, to give better cohesion and greater rigidity, as well as thermoplastics (e.g. polypropylene), for added flexibility, and thickening agents (e.g. colophane or polyisobutylene) for improved melt-viscosity.
Patent DE-2520332-A1 (DE)
Title: Safety hook between chains - has spring-loaded lever on twin support arms
Inventor: SPERBER ALFRED
IPC: A01K1/064
Filed: 1975-05-07
Abstract: The suspension hook provides speedy detachment of the chain with no risk of inadvertent disconnection. The hook can be detached, however, even when the chain or cable is under a high tension loading. Two fixed arms (4, 5) project from the base plate (1) of the hook (2). These form a jaw (7) with the hook end. A pivot lever (6) supported at the end of the fixed arms is spring-loaded (8) with a leaf spring. It acts as a closing gate with its face pressing against the hook. The line of force exerted by the chain (3) is virtually through the pivot axis (10) of the gate. The two arms are bowed and separated from one another. An extension to the design is for pulling chains where there is a semi-circular base plate with a hook at both ends.
